thanks
16,221

volunteer
so that's the speed we're looking for
16,221
100
[]
volunteer
Let's keep reading the question - after the appointment, what time is it?
16,221
101
[]
student
5:30
16,221
102
[]
volunteer
Right
16,221
103
[]
volunteer
And then the question says that he rode a bus for 4.8 miles to the soccer field after the appointment right?
16,221
104
[]
volunteer
But does it directly tell you how many minutes he rode a bus to the soccer field?
16,221
105
[]
student
no but the speed there
16,221
106
[]
volunteer
Exactly
16,221
107
[]
volunteer
So why don't we first set minutes as an unknown "x"?
16,221
108
[]
student
yes
16,221
109
[]
volunteer
And you said the speed is 0.106 mi per min
16,221
110
[]
volunteer
What do you get for x?
16,221
111
[]
student
wait let me backtrack
16,221
112
[]
volunteer
Yep what are you confused about?
16,221
113
[]
student
ok i understand
16,221
114
[]
volunteer
Sounds good. So what's x?
16,221
115
[]
student
0.106 x 4.8?
16,221
116
[]
student
or divison
16,221
117
[]
volunteer
division
16,221
118
[]
volunteer
cuz here 'x' is an unknown letter, not a multiplication sign
16,221
119
[]
student
0.508
16,221
120
[]
volunteer
You sure you did 4.8/0.106?
16,221
121
[]
student
45.2
16,221
122
[]
volunteer
So roughly 45 minutes right
16,221
123
[]
student
yeah
16,221
124
[]
volunteer
And the appointment ended at 5:30pm
16,221
125
[]
volunteer
so 45 minutes after 5:30pm is what time
16,221
126
[]
student
6:15
16,221
127
[]
volunteer
Is Leo on time for his 6:30pm soccer practice?
16,221
128
[ { "pii_type": "PERSON", "surrogate": "Leo", "start": 3, "end": 6 } ]
student
yes he is early
16,221
129
[]
volunteer
Right? That's it
16,221
130
[]
student
Thank you alot
16,221
131
[]
student
Just 2 more simple questions
16,221
132
[]
volunteer
Ofc go ahead
16,221
133
[]
student
is number 18 just distributing?
16,221
134
[]
volunteer
Yeah distribution
16,221
135
[]
student
and how do you solve 3?
16,221
136
[]
volunteer
I see you added 8 on each side for the first step
16,221
137
[]
volunteer
You're actually on a right track
16,221
138
[]
volunteer
First multiply each side by 4 and show me what you get
16,221
139
[]
student
is that correct
16,221
140
[]
volunteer
Yep that's correct
16,221
141
[]
volunteer
And divide each side by 2?
16,221
142
[]
student
thats the way my teacher wants
16,221
143
[]
volunteer
Oh ok that's no problem
16,221
144
[]
volunteer
You can still divide each side by 2 after distribution
16,221
145
[]
student
does the left side fully cancel out
16,221
146
[]
student
and we are only left with right
16,221
147
[]
volunteer
If we divide both sides by 2, it's gonna give us:
16,221
148
[]
volunteer
Are you confused with the concept of dividing both sides?
16,221
149
[]
student
no
16,221
150
[]
volunteer
Then do you get how I got to r-3 = 161 by dividing both sides by 2?
16,221
151
[]
student
2 divided by 2r cancled out the 2 just leaving r, 2 divided 6 is 3, 2 divided 232 is 116]
16,221
152
[]
volunteer
Yep exactly
16,221
153
[]
volunteer
So can we solve for r now?
16,221
154
[]
student
164 final answer?
16,221
155
[]
volunteer
Correct
16,221
156
[]
volunteer
That's how you solve that question
16,221
157
[]
volunteer
Mix of multiplication, division, and addition
16,221
158
[]
student
Thank you
16,221

I just realized this is going to be a long year
16,221
160
[]
student
this is so hard and i just started school
16,221
161
[]
student
Have a good night
16,221
162
[]
volunteer
Yeah it's hard cause you're learning a lot of new stuff in algebra 1
16,221
163
[]
volunteer
But guess what
16,221
164
[]
volunteer
You're gonna be reusing the same concepts you learned in algebra 1
16,221
165
[]
volunteer
Which means it's only gonna get easier and easier over time
16,221
166
[]
student
Thats great
16,221
167
[]
volunteer
So don't worry it's just one challenge you need to overcome
16,221
168
[]
student
Thank you for making me feel better, Have a good night!
16,221

volunteer
Alright have a good night!

hello i need help with 8.2 apply properties of rational exponents
16,143
1
[]
volunteer
Do you have a homework assignment on this? Could you post an example?
16,143
2
[]
student
yup
16,143
3
[]
student
give me 5 min
16,143
4
[]
student
im trying to finding it
16,143
5
[]
volunteer
Ok no problem
16,143
6
[]
volunteer
This seems to be a different concept than the rational exponents. Did you want help on the composite functions?
16,143
7
[]
volunteer
We can do that
16,143
8
[]
student
yh that
16,143
9
[]
student
mb
16,143
10
[]
volunteer
Ok so if we go through this machine analogy it might make more sense
16,143
11
[]
volunteer
It might be easier if I speak into the mic
16,143
12
[]
volunteer
Hello, can you hear me?
16,143
13
[]
volunteer
Mhm
16,143
14
[]
student
Yeah, I can hear you
16,143
15
[]
student
Oops
16,143
16
[]
volunteer
OK. All right. So
16,143
17
[]
volunteer
I think it would make sense first.
16,143
18
[]
volunteer
if we
16,143
19
[]
volunteer
look over what functions are. So, could you fill out
16,143
20
[]
volunteer
this table
16,143
21
[]
volunteer
with VFX
16,143
22

volunteer
So
16,143
23
[]
volunteer
it says GFX is
16,143
24
[]
volunteer
3 X
16,143
25
[]
volunteer
minus 2
16,143
26

and X is uh
